摘要
滹沱河饶阳段主流相、边滩相和堤外平地表土花粉分析表明,地处半干旱的华北平原,其河流沉积物的表土花粉组合主要来源于空气中的花粉雨其木本植物花粉以外来花粉成份为主,草本植物花粉主要由当地的草本植物成份组成。表土花粉可能成为冲积物花粉的一部分。
Pollen analysis of surface samples from the river course, point bar and overflow area in Raoyang section of the Hutuo River revealed that the surface pollen in the fluvial deposits in the semi-arid North China Plain mainly stemed from the pollen rains in the atmosphere, and the xylophyta pollen was mainly outside origin, while the herbaceous pollen was mainly local origin. Surface pollen may be a part of the alluvium pollen.
